In this paper, a control scheme based on Lyapunov's stability theory is proposed for connection of distributed generation (DG) resources to electrical grids via power electronic converters. The dynamic analysis of the DG system is first carried out, and then the proper switching state functions of grid-interfacing converter are obtained for stable operation of DG unit. Unlike classical control techniques,...
This paper deals with integration of distributed generation (DG) units to three-phase four-wire distribution networks utilizing power electronic converters. A control strategy that is based on feedback linearization technique is proposed in this paper which generates the switching state functions of the voltage source converter (VSC) as the heart of the interfacing structure between DG units and distribution...
A change in dynamics and operational characteristics of power systems is what shall be expected with the increase in the penetration of PV systems. This paper deals with a major PV penetration issue “dynamic stability” through proposing a modified control strategy that enables the PV system to damp out electromechanical oscillations as an ancillary service. The small signal and dynamic stability of...
